Patent CA-2176131-A1 (CA)
Inventor: LOGSTON GARY L
IPC: H04N7/167
Filed: 1994-11-03
Abstract: A digital video, audio and data distribution system which enables a set-top terminal (STT) associated with a customer's television set or other information presentation device to request interactive digital video, audio and data services from a service provider (SP) through the use of control system messages transmitted via a hi-directional signalling path. The requested interactive service is transmitted from the service provider over a portion of the bandwidth of a broadband transmission network which is dedicated to interactive digital services. A Video Session Connection (VSC) is provided for setting up and maintaining interactive sessions between the set-top terminal and a video service provider during the time the interactive programming is provided to the customer. The set-top terminal and service provider establish the Video Session Connection via a two-way signalling path within the bandwidth of the transmission medium into the customer's home. Applications of the system of the invention include "movie on demand" services where the set-top terminal not only requests a movie to be transmitted from the service provider for immediate transmission, but also the bi-directional command channel permits the set-top terminal to control the video presentation by sending commands such as Play, Pause, Fast-Forward and the like to the Service Provider while the movie is being transmitted. Other applications of the invention include on-line data retrieval services, shop at home services and other services which require the use of an interactive connection.

Title: Biased routing arbitration of message traffic in a communications network
Inventor: KRAUSE JOHN C
IPC: G06F13/40
Filed: 1996-06-05
Abstract: A data communicating device, having a number of inputs whereat data is received for communication from one of a number of outputs of the device, includes apparatus for selecting one of the inputs based upon a comparison of accumulated bias values that can change over time when an input is kept waiting. Each input is provided an assigned bias value from which is developed the accumulated bias value that is compared with that of other inputs arbitrating for access to an output. The output selects one of the inputs, based upon the comparison, and the accumulated bias value of the selected input is diminished by the sum of the assigned bias values of the inputs participating in the arbitration, but not selected, while the accumulated bias values of the other participants are each increased by their corresponding assigned bias values. Thereby, numbers of inputs having data destined for the same output will have their chance of gaining access to the output increased the longer they wait; conversely, inputs which do gain access have their chances for immediate subsequent access decreased in favor of allowing other inputs access.

Abstract: Converting heat in a primary fluid (e.g., steam) to useful energy by multistage expansion of the primary fluid, heating of a multicomponent working fluid in a separate closed loop using heat of the primary fluid, and expansion of the multicomponent working fluid.  The primary fluid in a vapor state is expanded in a first stage expander to obtain useful energy and to produce a partially expanded primary fluid.  The partially expanded primary fluid stream is then separated into liquid and vapor components and split into a vapor stream (which is expanded in a second stage expander) and a further primary stream (which used to heat the multicomponent working fluid).

Title: Traceback for viterbi decoder
Inventor: THOMAS RICHARD JAMES
IPC: H03M13/41
Filed: 1997-02-26
Abstract: In a traceback unit for an M-step Viterbi decoder for a convolutionally encoded data stream, each of the traceback stages has a group of K input wires representing Kpossible candidate states. A bank of K multiplexers selects one of 2M of the input wires according to M bits of traceback data. The K multiplexer outputs feed a succeeding traceback stage. M groups of K wires carry the traceback data, with each wire being connected to a selection line of each multiplexer. At the output of the traceback unit an identification circuit identifies a subgroup of the K possibilities which has a maximum number of candidate states remaining therein. The arrangement obviates the need for retiming between every traceback stage.

Patent CA-2202967-A1 (CA)
Title: Overvoltage suppressor
Inventor: SCHMIDT WALTER
IPC: H01T4/06
Filed: 1997-04-17
Abstract: The overvoltage suppressor contains two connecting fittings which are spaced apart from one another along an axis (z) and between which at least one cylindrical varistor element is arranged. The connecting fittings and the at least one varistor element are braced with respect to one another, forming a contact force, to form a mechanically robust active part of the overvoltage suppressor. The active part is sheathed by a molded housing made of insulating material. In each case, one material cutout is formed in each of the two connecting fittings with a section which runs essentially transversely with respect to the axis (z), is designed in the form of a slot and extends from the outer surface of the fitting to beyond the axis (z). A loop, which absorbs the contact force, is inserted into the sections, which are in the form of slots, in the region of the loop ends beyond the axis (z), and each of the two loop ends rests on in each case one surface which bounds the section which is in the form of a slot. The overvoltage suppressor is distinguished by good mechanical and electrical characteristics and can be produced in a particularly cost-effective manner.

Title: Centrifugal force drive machine
Inventor: MARSH RICHARD O JR
IPC: F03G3/00
Filed: 1995-01-12
Abstract: The centrifugal force drive machine for generating force in a controlled direction is provided. The machine includes a machine frame (2) having a shaft (4) mounted thereto for rotation about its axis (A). The drive mechanism is provided to rotate the shaft (4) about its axis (A). At least one mass (8) is mounted on the shaft (4) for rotation therewith. Each mass (8) has a center of gravity (CG) which is moveable radially with respect to the shaft (4) between the position in which the mass is rotationally balanced about the shaft (Fig. 1) and a position in which the mass is unbalanced (Fig. 3). A control member (14) in an operative connection  between the mass (8) and the frame (2) is provided to constrain radial movement of the mass (8) between the balanced position and the unbalanced position during each revolution thereof. When a mass is in the unbalanced position, the centrifugal force generated by the rotation of the mass is transmitted to the control member (14), thereby generating a linear force in the controlled direction (CD).
